Subject pretty much says it all. USB autosuspend since 3.10 is non-optional: http://www.mjmwired.net/kernel/Documentation/usb/power-management.txt (search for "3.10") This change should be cared of in powertop ebuilds which are currently complain about not enabled CONFIG_USB_SUSPEND when built with >=3.10 kernel. Reproducible: Always
+ 20 Jul 2013; Rick Farina <zerochaos@gentoo.org> -powertop-2.2-r1.ebuild, + -powertop-2.2-r2.ebuild, powertop-2.3.ebuild: + migrate USB_SUSPEND to PM_RUNTIME per bug 477280 Thanks for the report
sys-power/powertop-9999 still depends on CONFIG_USB_SUSPEND.
thanks for keeping me honest, I missed that when I was updating. fixed.
